Direct imaging of sub-parsec binary SMBHs in the central galaxy of the NGC 5044 group
Francesco Ubertosi, Gerrit Schellenberger, Ewan O'Sullivan +7
Binary active galactic nuclei (AGN) consist of two supermassive black holes (SMBHs) hosted in a single galaxy that are simultaneously accreting gas. These systems are key to unders…
The SKA View of Cool-core Clusters: Evolution of Radio Mini-halos and AGN Feedback
Myriam Gitti, Paolo Tozzi, Francesco Ubertosi +12
In about 70 per cent of relaxed, cool-core galaxy clusters, the brightest cluster galaxy (BCG) is radio loud, showing non-thermal radio jets and lobes ejected by the central active…
CHEX-MATE: A LOFAR pilot X-rayradio study on five radio halo clusters
M. Balboni, F. Gastaldello, A. Bonafede +24
The connection between the thermal and non-thermal properties in galaxy clusters hosting radio halos seems fairly well established. However, a comprehensive analysis of such a conn…
Milliarcsecond Localisation of the Hyperactive Repeating FRB 20220912A
Danté M. Hewitt, Shivani Bhandari, Benito Marcote +23
We present very-long-baseline interferometry (VLBI) observations of the hyperactive repeating FRB 20220912A using the European VLBI Network (EVN) with an EVN-Lite setup. We detecte…
Are radio minihalos confined by cold fronts in galaxy clusters? Minihalos and large-scale sloshing in A3444 and MS 1455.0+2232
Simona Giacintucci, Tiziana Venturi, Maxim Markevitch +3
We present radio and X-ray studies of A3444 and MS1455.0+2232, two galaxy clusters with radio minihalos in their cool cores. A3444 is imaged using the Giant Metrewave Radio Telesco…
Jet reorientation in central galaxies of clusters and groups: insights from VLBA and Chandra data
Francesco Ubertosi, Gerrit Schellenberger, Ewan O'Sullivan +8
Recent observations of galaxy clusters and groups with misalignments between their central AGN jets and X-ray cavities, or with multiple misaligned cavities, have raised concerns a…
